What's the point of this sarcastic comment? Do you think that some people claim that Rust's memory safety guarantees mean that a Rust program is incapable of crashing or having a bug? This is a dumb thing to claim certainly, but I'm not aware of anyone actually making this claim.

I'm also not sure what you're getting at with the comment about exception handling being lame. I think the ML/Haskell inspired model that Rust uses of having a parameterized Result type for fallible operations is generally better than exceptions for a variety of reasons (although maybe better Exception semantics could help with some of this), but what does this have to do with match blocks?
